RODNEY BUTTERFIELD, OF CHICAGO, ILLINOIS.

LAST-BLOCK FASTE'NER.

SPECIFICATION forming part of Letters Patent No. 270,013, dated January 2, 1883.

Application filed June 15, 1882. (Model.)

Toall whom it may concern Belt known that I, RODNEY BUTTERFIELD,

ledge of thelast against which the block bears,

and fitted in the block to be turned by the lasthook, for which an eye is provided in the upper endof the rod, together with a hook at the upper end of the block, which engages'a staple in the last when the block is shoved down to its place on the last, making substantial fastenings to the block, easy to manipulate and not liable to get out of order, all as hereinafter lully described.

Reference is to be had tothe accompanying drawings, forming a part ot'this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure lis a longitudinal sectional elevation of a last and block with my improved fastenings; and Fig. 2 is a transverse section of the last and the rod for fastening theblock thereto, the section being taken on the line a: a; of Fig. 1.

a At the shoulder a, at the bottom of the score in the last I; for the instep-block c, I arrange a lockingplate, d, over the recess c, with a slotted ho1e, f, for the pointed T-head h of a rod, i, which I arrange in a hole bored longitudinally through block 0, and secured by a plate, j, andcollar k or other approved means,

against moving lengthwise in said hole. In the upper end of rod 2', which projects a lit- 'tle above the upper end of block 0, I-arrange an eye, l, whereby the rod may be readily shifted a quarter-turn on its axis to lock it with plate d. and unlock it therefrom.

Together with the said fastening above described for the lower end of the last-block, I proposeto employ the hook it on the under side of the upper end of block 0, and the staple 0, attached to the last in-the recess 1), so arranged that the hook will engage with the staple when head h enters slot f, and secure the upper end of the block against lifting or shifting laterally on the last.

These devices are simple and reliable and easy to operate, as will readily appear by inspection of the drawings.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the last 11, having recess 0, covered by the slotted locking-plate a, of the rod t, passing longitudinally through the last-block c, and having a T-head, h. projecting beyond the forward end ofsaid block, substantially as described, and for the purpose set forth. u

2. The combination, with the last I), having the recess 0, covered by slotted. locking-plate d, and the eye or staple 0, arranged in a recess, 12, in said last, of the T-headed and eye-ended locking-bolt 11, passing longitudinally through the last-block c, which is provided with the hook n on the lower surface of its upper end, substantially as described, and for the purpose set forth.

3. The combination, with the last I) and lastblock 0, of the T-headed and eye-ended locking-boltvl and locking-plate d, also hook n and staple 0, substantially as described.

R. BUTTERFIELD.
